RAIL orrAIR.

Application filed April 1, 1922.; Serial No. 548,686.

1 '0 all whom it may concern Be it known that 1, CHARLES PASCAL, a subject of th King of Great Britain, and residing at the city of Montreal, in the Province of Quebec, in the Dominion of Canada,

novel. features of constructionpointed out broadly and specifically in the claims for novelty following a description in detail of the preferred form of the invention.

The objects of the invention are to elinii nate as far as can readily be done the dangers to life and property resulting from accidents due to broken or loose joints; to prolong the life of the rail lines by saving the rails at the joints and forming what is substantially a continuous line of rail; to economize in rolling stock and avoid many of the numerous repairs necessaryin present day practice to locomotives and cars; to effect a great saving in maintenance charges in regard to the roadbed and upkeep generally of the rail line; to enable-the railway companies to reduce insurance disbursements for derailing accidents; and generally to prevent dislocation of joints and the grave consequences as a result therefrom; and to effect improvements on my railchair Patent No. 1,399,572, December 6th 1921.

In the drawings, Figure 1 is a perspective view of the chair showing the rails in cross section set therein.

Figure 2 is a cross sectional view of the joint illustrated in Figure 1.

Figure 3 is a plan view of the underside of the base plate broken away and showing the bolt head recesses.

Figure 4 is a perspective view of the ti htening key.

igure 5 is a cross sectional view of the rail showing an end view of the chair and. electric connectors.

Figure 6 is a perspective detail of an upper electric connector.

Figure 7 is a perspective detail of a base electric connector. 7

Figure 8 is a perspective detail of a filler strip electric connector.

Like numerals of reference indicate cor responding parts in the various figures.

Referring to the drawings, the base 1 is.

formed with the longitudinal rail'base recess 2 on the one side and on the other side with the longitudinal abutment 3 preferably undercut to form the key retaining wall 4. The rail ends 5 and 6 are supported on the base 1 and meet intermediately of the length thereof, preferably at or about the centre,

the bases 7 and 8 of saidrails extending into the recess 2-at one side and at theother side meeting the inserted filler key 9 which is tapered andfits under the wall 4: and has the pin holes 10 near its smaller end for the insertion of a cotter pin'lito fasten the key to its place.

The joint plate 12 on the one side of the rails 5 and 6 extends from the bases to the under sides of the rail heads and the bolts 13 project through the rail webs and are fastened by the nuts 14 to the joint plate 15.

The joint plate 15 also rests on the rail bases and extendsto the rail heads, but is formed with an outwardly projecting extension 16, over base, filler key and abutment and at the outer edge is slotted at 17 for the bolts 18. The latter bolts 18 extend upwardly through the base 1 and have square or polygonal heads which are recessed in correspondingly shaped holes 19in the under side of the base 1 and are heldby the nuts 20 screwed thereon and tightened to the extension 16.

To electrically join the rails 5 and 6 a copper plate 21 may be laid on the rail surface of the base 1, either for the whole length and turned over at-the ends 22, or only fora part of the length and countersunk. 0

Another electric connector 23 is n strip form and fills in between the rail-bases and wall of the recess 2 and may be turned over at the ends 24, or this recess may be lined by conducting material in any suitable manner. 7

The-third electric connector 25 is -1ntr0- duced between thejoint 15 under its extension 16 and over the rail bases, filler key and longitudinal abutment 8 and is turned over the latter at the ends 26 and inside the plate 15 at the inner longitudinal edge 27, thereby completing the electrical connection of the rails for. the strongest current used or pro viding electrical connection for a weak current for signal or other purposes.

In the use of this invention the rail ends are laid in the base and the filler key and as I joint plates properly positioned and secured and according to the particular circumstances the necessary electrical connectors introduced.

The rails are then joined up in continuous lengths irrespective of the rail ties, as this joint is equally efiicient between ties because it forms a binder for the rails that cannot readily be shaken loose, thereby reducing the vibration in the passing vehicles due tothe rail joints and maintaining a continuous line of rail.

What I claim is:

1. In a rail chair, a base having a rail base recess at one side and a longitudinal abutment on the other side, a joint plate extending over said abutment and adapted to extend over the base of the rail and upturnedunder the rail head and having bolt slots from the outer edge, bolts in said slots and suitably recessed in the base and a filler key betvveen'said abutment and the bases of the rails supported and fastened therein.

2. In a rail chair, a base having a rail bolts holding the plates adapted to extend through the rails.

In a rail chair, a base longitudinally recessed for rail ends, a filler key slightly wedge shape and having pin holes at the small end, a cotter pin forming afastener. joint plates bolted together through the rail Webs and bolts through one joint plate and said base and having-their heads recessed and locked in the underside ofsaid baseand nuts on their upper ends.
